# jr: command-line JSON processor for Rubyists jr is [jq](http://stedolan.github.io/jq/) like JSON processor. Its script can be written not a specific language but Ruby!  ## Installation Add this line to your application's Gemfile: gem 'jr-cli' And then execute: $ bundle Or install it yourself as: $ gem install jr-cli ## Usage jr filter can be written in Ruby! ``` $ jr [options] [file...] ``` You can also read JSON not from files but from STDIN. ### options ``` --require FILE require the FILE before execution -c, --compact-output output each JSON in single line -f, --from-file FILE read filter from file -r, --raw-output output strings as raw output -R, --raw-input read each line as string -C, --color-output output with colors even if writing to a pipe or a file -M, --monochrome-output output without colors -n, --null-input use null as input instead of any files --unbuffered output each JSON without buffering ``` ## jr filter tutorial Let's process JSON of GitHub API! At first, download JSON of repos into your local to avoid API rate limit. ``` $ curl -s 'https://api.github.com/users/yuya-takeyama/repos?per_page=100' > repos.json ``` ### Unwrap Array with `Enumerable#unwrap` Because response from `GET /users/:username/repos` is wrapped with `Array`, unwrap it using `Enumerable#unwrap`. It's a built-in method of jr. You'll get stream of JSON reperesents repositories. ``` $ jr 'unwrap' repos.json ``` ### Aggregate data with methods of `Enumerable` `Enumerable` has many useful methods and you can transform data with them. ``` $ jr 'unwrap.group_by(&:language).map{|k, v| [k, v.size] }.sort_by{|k, v| -v }' repos.json [ "Ruby", 28 ] [ "PHP", 22 ] [ "Go", 17 ] (...omitted...) [ "VimL", 1 ] [ "CoffeeScript", 1 ] [ "Perl", 1 ] ``` ### Output as text You can transform JSONs into String and output as raw text using `-r` option. ``` $ jr 'unwrap.group_by(&:language).map{|k, v| [k, v.size] }.sort_by{|k, v| -v }.map{|l, s| "#{s}\t#{l}" }' -r repos.json 28 Ruby 22 PHP 17 Go 12 JavaScript 11 3 CSS 2 Shell 2 C 1 VimL 1 CoffeeScript 1 Perl ``` ## Basic mechanism It's helpful to know jr's basic mechanism. Shortly, jr is implemented like below. ```ruby json_enumerator.instance_eval { your_jr_filter_runs_here } # And print its result ``` ## Contributing 1.
